Transliterator::transliterate -- transliterator_transliterateTranslittère une chaîne de caractères


Style orienté objet

public Transliterator::transliterate(string $string, int $start = 0, int $end = -1): string|false

Style procédural

    Transliterator|string $transliterator,
    string $string,
    int $start = 0,
    int $end = -1
): string|false

Transforme une chaîne de caractères ou seulement une partie en utilisant un translittérateur ICU.

Liste de paramètres


Dans la version procédurale, soit un Transliterator soit une chaîne de caractères depuis laquelle un Transliterator peut être construit.


La chaîne de caractères à transformer.


L'index de départ (en unité UTF-16) depuis lequel la chaîne commencera à être transformée, inclusif. Les index commencent à 0. Le texte avant cet index restera inchangé.


L'index de fin (en unité UTF-16) indiquant la fin de la transformation, exclusif. Les index commencent à 0. Le texte après cet index restera inchangé.

Valeurs de retour

La chaîne de caractères transformée en cas de succès, ou false si une erreur survient.


Exemple #1 Conversion des échappements en unité UTF-16

= "\u304A\u65E9\u3046\u3054\u3056\u3044\u307E\u3059";
transliterator_transliterate("Hex-Any/Java", $s), "\n";

//maintenant, l'opération inverse avec un caractère supplémentaire
$supplChar = html_entity_decode('&#x1D11E;');
mb_strlen($supplChar, "UTF-8"), "\n";
$encSupplChar = transliterator_transliterate("Any-Hex/Java", $supplChar);
//affiche 2 unités UTF-16 encodés
echo $encSupplChar, "\n";
//et le retour...
echo transliterator_transliterate("Hex-Any/Java", $encSupplChar), "\n";

I pretty much like the idea of hdogan, but there's at least one group of characters he's missing: ligature characters.
They're at least used in Norwegian and I read something about French, too ... Some are just used for styling (f.e. fi)

Here's an example that supports all characters (should at least, according to the documentation):
(transliterator_transliterate('Any-Latin; Latin-ASCII; Lower()', "A æ Übérmensch på høyeste nivå! И я люблю PHP! fi"));
// string(41) "a ae ubermensch pa hoyeste niva! i a lublu php! fi"

In this example any character will firstly be converted to a latin character. If that's finished, replace all latin characters by their ASCII replacement.

Sorry, for posting it again, but I found a bug in my code:

If you have a character, like the cyrillic ь (a soft-sign - no sound), the "Any-Latin" would translate it to a prime-character, and the "Latin-ASCII" doesn't touch prime-characters. Therefore I added an option to remove all characters, that are higher than \u0100.

Here's my new code, including an example:

var_dump(transliterator_transliterate('Any-Latin; Latin-ASCII; [\u0100-\u7fff] remove',
"A æ Übérmensch på høyeste nivå! И я люблю PHP! есть. fi"));
// string(50) "A ae Ubermensch pa hoyeste niva! I a lublu PHP! est. fi"

Another approach, I found quite helpful (if you by no way want to remove characters ...), try to use iconv() in addition. This surely will just return ASCII characters.


Also an example here:

var_dump(iconv("UTF-8", "ASCII//TRANSLIT//IGNORE", transliterator_transliterate('Any-Latin; Latin-ASCII',
"A æ Übérmensch på høyeste nivå! И я люблю PHP! есть. fi"));
// string(50) "A ae Ubermensch pa hoyeste niva! I a lublu PHP! est'. fi"

You can create slugs easily with:

function slugify($string) {
$string = transliterator_transliterate("Any-Latin; NFD; [:Nonspacing Mark:] Remove; NFC; [:Punctuation:] Remove; Lower();", $string);
$string = preg_replace('/[-\s]+/', '-', $string);
trim($string, '-');

slugify("Я люблю PHP!");

There are some possibly undesirable conversions with ASCII//TRANSLIT//IGNORE or your users may require some custom stuff.

You might want to run a substitution up front for certain things, such as when you want 3 letter ISO codes to replace currency symbols. £ transliterates to "lb", for example, which is incorrect since it's a currency symbol, not a weight symbol (#).

ASCII//TRANSLIT//IGNORE does a great job within the realm of possibility :-)

When it doesn't do something you want it to, you can set up a CSV with one replacement per line and run a function like:

function stripByMap($inputString, $mapFile)
$csv = file($mapFile);
foreach($csv as $line)
$arrLine = explode(',', trim($line));
$inputString = str_replace($arrLine[0],$arrLine[1],$inputString);
return $inputString;

or you can write some regexes. Transliterating using ASCII//TRANSLIT//IGNORE works so well that your map probably won't be very long...

OOP version :

= 'àáâãäçèéêëìíîïñòóôõöùúûüýÿ
$rule = 'NFD; [:Nonspacing Mark:] Remove; NFC';

$myTrans = Transliterator::create($rule);
